600 graw blue crab, cleaned and halved
40 gscallions, cut into 5 cm lengths
20 ggarlic cloves, sliced
15 gfresh ginger, sliced
10 gred chili, sliced

Soy marinade

180 mllight soy sauce
120 mlwater
30 grice syrup
15 gsugar
15 mlrice vinegar
8 gtoasted sesame seeds
5 mlsesame oil

Instructions

1
Check that the raw crab is sushi-grade or specifically intended for raw marinating, very fresh, and kept thoroughly chilled. Pat dry if needed, then place the cleaned, halved crab in a non-reactive container in a single snug layer. This dish is not safely achievable from ordinary unreliably sourced raw crab.
2
Prepare the aromatics: cut the scallions, slice the garlic and ginger, and slice the red chili. Scatter half of them under and around the crab, reserving the rest for the top so the marinade contacts all surfaces evenly.
3
In a bowl, stir the soy sauce, water, rice syrup, sugar, rice vinegar, toasted sesame seeds, and sesame oil until the sugar dissolves. Taste the liquid: it should be deeply savory, lightly sweet, and slightly sharp. Pour it over the crab, then add the remaining aromatics on top. Make sure the crab is mostly submerged; press down lightly or cover directly with parchment if needed.
4
Cover and refrigerate immediately. Marinate for at least 24 hours and up to 36 hours, turning once halfway through for even seasoning. The flesh should become slightly translucent and well seasoned but still smell clean and marine, never fishy or sour.
5
To serve, transfer the crab and some of the aromatics to chilled plates and spoon over a little marinade. Serve very cold, ideally with hot rice. Eat promptly and keep the dish refrigerated until the moment of serving.

Notes

•Because this is a raw crab preparation, the true minimum total time is far longer than the requested 10 minutes; safe marination and strict cold storage are essential.
•For the best texture, use female blue crab or Korean flower crab when available, and ask your fishmonger to clean and cut the crab for raw use.
•Do not reuse the marinade unless it is boiled thoroughly and used only for a cooked application.
•A small spoon is useful for scooping the roe and juices from the shell, traditionally one of the most prized bites.
